Contender barrel problem....

[screwcutter]

All barrels TC manufactured, all early 90s & earlier.

The hotshot barrel works fine right now with the original one piece lug back on it. The two piece that I grinded quite a bit (at least I thought I had go too far) works fine on the hotshot. Can't get it to work with the 7tcu barrel it came on.

Going to look and see if it had the worn spots screw press suggested, not sure what else to look at.

Easy open frame should be available for me to try the barrels on this weekend.

I wish you much luck.. stay at this...
Keep working on that sacrificial Lug... it may yet reveal some Hint!!! May as well leave it with the TCU barrel at this point!!
Intriguing.. yes

Just occurred to me... that rimless extractor on the TCU barrel.... Does it push all the way in???? I would be tempted to close that barrel with the Extractor removed... they must be fitted correctly..or..of course, give problems.... Grabbing at Straws Now!!!!

From the web, easier than taking one apart.
The other 2 pic are out of mine to show the markings.
I have a mix match of new & used barrels, my problem
barrel started out on this frame.
I polished, fit and refit locking lugs replaced, before I figured
it out.

Still having a hard time envisioning the extension contacting the trigger guard.. is it possible the screw holding tension on triggerguard spring was too Short???
With Triggerguard removed, I place it in position against barrel lug... on None of mine, is the "ramps" even at the polished portion...they sit all the way down at the root, unused part of the Ramp when assembled, unless the screw was shorter.. which at some point would prevent any Lockup.
